It all started with us living together. by us I meant Beast and my besties. We're all couples and everything's good you know? That is, until someone started killing us, one by one.

Bumping into a stranger with a buch of crazy screaming fan girls aint such a good idea. Trust me. I know.

Beast, in this story are aged 16-17-18 etc. They are one of the most feared gangs in Seoul, maybe even Korea. Their fighting and their looks are legendary. Girls fall at their feet, boys want them dead. But they are unbeatable. That is, until one day Hyunseung discovered his father married another woman and had a child. She is called Amy... And she, unknowingly, becomes their weakness.
